苜蓿干旱胁迫的生理响应及其分子水平的研究进展

Research Progress on Physiological Reaction and Molecular Level under Drought Stress in Alfalfa

苜蓿在干旱胁迫下的适应能力较强,能通过自身的生理代谢、结构发育和形态建造等方面适应干旱的环境条件。有关苜蓿的抗旱性研究一直以来都是牧草学研究的热点之一,研究领域也逐渐从形态水平发展到生理、生化及分子生物学等更深入的领域,并取得了很多有价值的研究成果。现对苜蓿在干旱胁迫下各项生理指标、基因工程及蛋白质组学的研究进行综述,并对研究中存在的问题及今后的应用前景进行了简单的讨论。

Alfalfa has quite stronger ability to adapte the drought stress by physiological metabolism, structure development and morphology construction. The research of how did alfalal resist drought is a hot in forage researches. The research is developing from physiology, biochemistry, molecular biology and even more in-depth field, and have gotten many valuable results. This paper reviewed the variety of physilogical indexs, genetic engineering and proteomics researches in alfalfa under drought stress, and briefly discussed the problems and future prospects in the research.
